I'm not a professional or stupid.

Well, I would have to agree with Keith. All the cams are too big for 1.6 rockers.

My suggestion was 1.5 rockers with the .490 cam.

I based this choice on the Edelbrock perf/rpm 64 cc head which recommends the .488 cam. The Edelbrock head only carries a 170 cc runner which is smaller than the 180 cc runner he is using. The 64cc head gives the same compression at 10.5 to 1. The .488 cam recommends 2800+ stall. Which is basically what he has. Thus, the .490 was the best choice.

Since he is determined to use the 1.6 rocker and a Comp cam. We will deduct the 7% gain from the 1.6 rocker. So, the .490 cam divided by 7% leaves a .4579 cam. Comp cams closest cam is the XE262H which has a .462 lift. Which is exactly what KeithB123 suggests.

My preference:
Crane cams 286H06
.465 lift, which is where we agree you want to be.
286 duration, which is longer than the XE262H
(duration is barely affected by the 1.6 rocker, only the lift).
